Regression estimates of the relationship between period of same‐sex marriage, male PrEP prescription rates and male PrEP‐to‐need ratios

	Male PrEP prescription rate per 100,000 males		Male PrEP prescription rate per 100,000 gay or bisexual males		Male PrEP‐to‐need ratio
	Adjusted incidence rate ratio	95% confidence interval	Adjusted incidence rate ratio	95% confidence interval	Adjusted mean difference	95% confidence interval
Year of same‐sex marriage
2004–2011	2.27	1.71–3.02	1.85	1.45–2.35	1.26	0.15–2.36
2012–2013	1.40	1.12–1.76	1.21	1.01–1.45	3.83	2.84–4.81
2014–2015	Reference		Reference		Reference
Year	1.65	1.59–1.70	1.65	1.60–1.71	1.09	0.85–1.33
Medicaid expansion	1.56	1.32–1.83	1.50	1.28–1.76	0.43	−0.53 to 1.38
Democratic governor	0.91	0.80–1.04	0.90	0.79–1.03	−0.24	−1.25 to 0.78

Note: For male pre‐exposure prophylaxis prescription rates per 100,000, generalized estimating equations negative binomial regression models were used to account for repeated observations of states with a log link, and log population offset. For male pre‐exposure prophylaxis‐to‐need‐ratio, we used generalized estimating equations linear models to account for repeated observations of states.
